200-700 g/d fruits and vegetables consumption decreases frailty

Objectives:
Does fruits and vegetables (FVs) consumption reduce risk of frailty?

Study design:
This review article included 10 cohort studies and 4 cross-sectional studies with 18,616 subjects with frailty and 101,969 controls (persons without frailty).

Based on the NutriGrade score, the quality of evidence for a protective effect of fruits and vegetables consumption on frailty was "moderate".

Results and conclusions:
The investigators found in 7 cohort studies for the highest versus lowest category of fruits and vegetables consumption a significantly reduced risk of 35% for frailty [RR = 0.65, 95% CI = 0.50 to 0.84, I2 = 81%].

The investigators found that every 200g per day increment in fruits and vegetables consumption was significantly associated with a 14% lower risk of frailty.
The risk of frailty decreased linearly up to fruits and vegetables consumption of 700 g/d, with flattening the curve at higher intake.

The investigators found that pooled analysis regarding fruits and vegetables separately did not indicate a significant association with the risk of frailty.

The investigators concluded that 200-700 g/d fruits and vegetables consumption decreases risk of frailty. Further large-scale prospective cohort studies are needed to reach more confident conclusions.
